Abstract

We present and analyze the unique phenomena of enhanced THz transmission through a subwavelength LiF dielectric rod lattice embedded in an epsilon-near-zero KCl host. Our experimental results in combination with theoretical calculations show that subwavelength waveguiding of terahertz radiation is achieved within an alkali–halide eutectic metamaterial as result of the coupling of Mie-resonance modes arising in the dielectric lattice.
